APIENTRY is an alias for WINAPI. WINAPI itself is a definition for the type of calling convention used for windows API calls, the stdcall. Basically this is explaining to the compiler how to handle the stack and arguments when calling this function.
One may also ask,
APIENTRY is an alias for WINAPI. WINAPI itself is a definition for the type of calling convention used for windows API calls, the stdcall.
Moreover, The main components of the WinAPI are: WinBase: The kernel functions, CreateFile, CreateProcess, etc WinUser: The GUI functions, CreateWindow, RegisterClass, etc WinGDI: The graphics functions, Ellipse, SelectObject, etc Windows API index on MSDN. Versions of the API are tied to the operating system version.
In this manner,
The windows compiler I use defines them both as __stdcall, so there should be no difference. WINAPI Use in place of FAR PASCAL in API declarations. If you are writing a DLL with exported API entry points, you can use this for your own APIs.
Accordingly,
WinAPI (also known as Win32; officially called the Microsoft Windows API) is an application programming interface written in C by Microsoft to allow access to Windows features. The main components of the WinAPI are: Windows API index on MSDN. Versions of the API are tied to the operating system version.
